rier 14.- Flow of air to, and fromthecy'lin- 'der 44 is controlledby a.`solen'oid-operated valve V2 imilar' to thevalveYl, air being received t rough-the-supply pipef45.. For" convenience in assembling 'and-. 'dissociating the parts, I have found"-ltffconvenient to 'carry thepivot pin41 v uponA the end` of .a threaded rod 46 which is threaded through a bracket 48 mounted upon or forminga part of the parison I nold carrier 14.v

Coperating with the neck ring -mold sections, and in alinement therewith, vis a tube' 50. through which is reciprocably mounted a pin 51 which,'at its inner end, is .provided with a tip. 52 whichis adapted to enter the .neck-forming pocket 5 3 of the neckring lmold in such manner as'to permit the glass .municate two passages- 58 and 59 `both. of

to flow around the pin to'form the neck of the completed article. The passage 54 which leads through the neck ring mold from the pocket 53 is slightly larger-than the portion of pin 5l which lies therein, the difference in diameter beingsufficient to permit fairly free passage of air .but not sufficient to permit passage of molten glass.l -Theportion 55y of the interior of tube 51 is somewhat larger than the pin 50 and the walls of this portion are perforated at 56 communicating with an annular passage 57 with which comwhich lead to atransverse passage 60 within i which is journaleda valve pin 61. Secured 'to the valve pin 61 are arms 63 connected by links (i4-,with a lever 465 by means of which the valve pin is oscillate'd, as will bc j fmade to appear.- Pin 61 at one lend is cham.- bered, as indicated at 66 (Fig.v 8) and a t the may "bebrought intermittently into-registry with an air supply passage 69 which combottom, of this chamber is formed a nipple v67 through which extends a passage 68 which I municates with -a-pipe 70.

the air pressure, said valve headcontrolling the communication between the the supply pipe-81.. Pivotally mounted uponbrackets 85 carried by the'carrier 14 is a cylinder 86 within 90 which is mounted .a piston .87, Asaid piston being' provided with arod 88 which at its pipe 81 and end carries apivotedcver plate 89. Piston rod 88 carries a collar 90 to which is pivoted one-endof a'link 91, the opposite end .being "95 pivoted upon the carrier 14 so that, as the.

piston is 'reciprocated 'from the position shown in'full lines in F ig. 3 to the position shown in vdotted lines 'in that ligure, Athe cover plate 89 will be carried over and de- 100- posited' upon the upper open end of the parison mold, as indicated in dottedA lines in Fig. 3. Passage of air or other motive fluid to and from the cylinder 86 is-control1ed by a valve V4V like the valveVl.

I `Aspreviously stated, the carrier 14 is provided -With trunnions 13 which are journaled in the bearings 12 of standards 11 and I provide-the following mechanism for indv verting the carrier so that the parison 1n-old, 110

may be first presented vwith its bottom end upward to-receive the molten glass and may then be inverted, as shown in Fig. 2, so

that the parison maybe delivered .to the blow mold t-,fMounted' upon suitable honi-.115. zontal-trunnions is acylinder 101/in which is mounted a piston carrying a rod 102 connected by the flexible links 103 with one end of carrier 14, the arrangement being such that reciprocation of the rod 102 will 120- cause oscillation of the carrier 14 and pro-Y duce oscillation of the cylinder 101. Flow of air to and from the cylinder 101 is con# trolled by a valve V 5 which is similar toene` hal-f of the valve V1, This valve is mechan- 125 icallyfoperated into its exhausting position byengagement with a cam 104 which operatesupon it as the cylinder 101 oscillates.

Pivoted 'at 105 -on the carrier 10 is a swingingmold support 106 which. carries a 13o."

pivot pin 107` upon which the mating halves 10S. 108 of the blow mold are hinged, said blow vmold sections cooperating with a bottom mold 109 mounted on` the carrier 101'. In order to intermittently swing the carrier 101' to bringI the blow mold into and out ot' alinement `with the parison, I attach links 111 which are also connected to arms 112 carried b v a'rock shaft 113. Rock shaft 113 carries an arm 11-1 which is pivoted to the end of a piston rod 115 carried by a piston within an oscillating cylinder 111 pivoted at 1.17 upon the carrier 11.). Flowot air to and from the cylinder 111'. is controlled by a valve \'1 similar to valve V1 and receiving it.,` supply of aiil through a pipe 11S.

The sections 10S, 108 of the blow mold are opened and `closed b v links 119 carried by levers 120 pivoted at 121 on carrier 1015, the said levers being moved by a toggle comprising the. links 122. 122 to the lioint or knuckle ot' which is connected the pistou rod 123 carried by a piston within the cylinder 124 which is pivoted M125 upon the arrier 101'. Flow of air to and from cylinder-124 is controlled by 'a valve V7 like valve Y1 and receiving its air from pipe 121'.

The apparatus just described may be provided with glass in any desired manner and in Figs. 1 and 2, l show an autonnitically operating shearing mechanism for cuttinggl ass from a punty stream. In this form the shears 131) are carried by a swinging carrier 131 plvoted at 132 on the mam support. 10.`

The details of this construction are not ma-` terial to the present invention and it is considered sutlicient to say that the shears 130 are intermittently operated by a lever acted on by the solenoid core 134 arranged within the coil 1335. The carrier 131 is connected by links 1315 and 13T with a piston rod 13S carried by a piston within a cylinder 130 pivoted at 140 on the carrier 10. Flow of air to and from cylinder '130 is controlled by a valve YS which is like valve V1.

The various movements of the mechanism a re controlled by the nlovement ofV the controller shaft 150 (Fig. 10) which is constantly rotatedby means ot' a gear 151 (Fig. 11) worm 152. shaft 132i. gearing 154 and a small motor 155. Shaft 15() insulated from the main body of the machine and is -connected to a main supply wire 151' by a 'spaced but it will be readily understood that the actual'spaeing will vary, dependent upon the relative time relationship between4 the successive movements desired. This adjust ment may be Iobtained b v providing slotted openings for the terminals, or by providing a large number of. closely arranged openings,

or in any other well known manner to ob-` tain the desired result, the arrangement be-v ing such that one turn ot' shaft 150 produces alternately engaged by the terminals rl and l', on the oscillating carrier Z300. Terminal is connected by a wire 1111 with the coil of valve YP the other end ot' said coil being grounded at 107. Terminal is connected b v a wire 10S with one coil ot' thc cover controlling valve V4 the `other ,coil being connected by awire 1119 with terminal f on the carrier 301) andthe two coils being grounded at 170. Terminal f is connected by a win` 171 with a terminal on the standard 1l and the terminal on thc carrier 300 is connected by a wire 1.72 to one coil ot valve \il the other coil being connected by a wire ITI with the terminal p on the carrier 200. Terminal cY connecter-'l by a wire 171 with a terminal cp on standard 11 and terminal c' on carrier Z500 is connected by a wire 17? to a wire 1131 which is connected to the coil ot" valve V3. 'l`ern1inal 1/ is connected by a wire 171' y with the coil of valve V5 which is grounded as indicated at 17T. For convenience in illustration.the coil ot' this valve V3 is shown in two positions in diagram (Fig. 10) towit. turn-over position l.` and turn over position and this` coil is therefore connected by a wire 17S with terminal (l. 'l`erminal hy is connected by a wire 170 with one otl the coils ot' valve YT the other coil being connected by a wire 180 with terminal and the two coils being grounded as indicated at 181. Terminal i is connected l, a wire 152 with the terminal fi. Terminal j is connected by a wire 183 toone of the coils \'1' the other coil being connected by a wire 184 with terminal n and the two coils being grounded as indicated at 155. Terminal is connected by a wire 1S1' with the terminal f/ on standard 11. Terminal m is connecttl` by a `wire 1ST with terminal m" on standard 11 and terminal Am on carrier 2100 is consol i sages 69 and 68 ale 77 so as to produce a suction 1n the neck connected by a wire 191. with terminal ep.' Terminal r is connected by a wire 192 with the coil ot a solenoid pump 193 the core 191 of which lies within a cylinder 195 into which oil is delivered through av pipe 196 and delivered through a-pipe 197. a spring 198 being provided tonormally hold thc core 194C up above thedelivery end of pipe 196 so that oil may flow into the cylinder 195, the arrangement being such that pipe 197'is directed toward the open uppeiI end 'of the parison mold and a small quantity of oil delivered intol the mold just before it receives its charge of glass. r y

Assuming the shaft 150 to be rotated in the direction indicated by the arrow and the brush 158130 be just going into contact with terminal t/the cycle of operation is as follows:

In this assumed position the carrier 300 will be in .the position' indicated in Fig. l and at that time terminals e', d and f will be in contact with the terminals ep, (Il, and fz?, respectively: the parison mold and neck ring mold will be in closed position; .the shear will be in the position shown in Fig. 2 and the blow mol d in the` position shown in Figs. 1 and The contact between brush 158 and terminal awill close the circuit through wire 160 and that coil of valve V8 which will cause an upward or expelling movementfof piston rod 138 which. acting through links 136'and 137 will swing the shear carrier 131 into the position shown in Fig-1 with the shear blades lying over the upper end of the blank mold. This movement of the shear carrier 131 brings lingers 201 into engagement with lever 65 so as to swing the valve pin 162 and ,cause finger 76 to engage valve 73 and allow a flow of air through pipes 75 and 70 and pasthrough the aspirator nozmold. This movement of lever 65 also throws the plunger 51 upwardly to bring itstip intoI the pocket 53 of the neck mold. Thereupon glass is deposited in the blank mold and will be sucked downwardly so as to form a proper neck in the neck mold around the tip 52. l Advance of arm 57 brings brush 158 into contact with terminal Z) which closes the circuit through wire 163 and coil.135 so as to actuate the shear and cut the glass from thesupply. Thereupon terminal 'c isengaged. closing the circuit through wire 161 and one coil of valve V8 so as to throw the shear back t'o the position shown inl Fig. 2 and withdraw plunger 50.

cut oj the suction, and register passage 79.

with passages 80 and 58.4 Contact with terminal d-'closes the circuit through wire 165, terminal Ill, terminal rl and wire 168 to one coil of valve V4 which thus admits air to the left hand end of cylinder 86 (Fig.

3) so as to move the cover 89 over the upper the vertical center.

end of the parison mold. Thereupon` contact with terminal c closes circuit through wire 174, terminal ep, terminal e. wire 175, part'of wire 166 and the coil of valve V3 so as to admit a small quantity of air through pipe 81 and passages 80, 79 and 58 into the cavity in the parison formed by the witlnlrfnval of the tip 52 when the shear carrier is thrown back to its normal position shown in Fig. 2. This preliminary blowing of the blank is accomplished very quickly, the terminal e being quite'sliort circl'lmferentially. Thereafter contact with terminal f' closes circuit through wire 171, terminal fi. terminal f. and wire 169 to the other coil ofvalve V-l thus causing a withV drawal of cover 89. 'Contact with terminal g closes circuit through wire 176 to the coil of valve V5 thus admittmg air into the upper end of cylinder 101 causing a reversal of the carrier 14 to the position shown in Fig. 2. As the cylinder 101 passes over A about the axis 100, valve V5 is i'nechanically so as to permit the air to exhaust from the cylinder as the oscillating n'iovement of the carrier 14 is completed. due to the slight preponderance of weight on themold Side' of the trnnnions 13. This inversion of carriver 14 carries ternnnal c', d, and f outof contact with terminals ep, (ZZ, and fz' and operated by the cam 101, v

brings terminals p', Z and 'i' into contact` v with the terminals cp, (ZZ, and fi, respectively, and also brings terminals 0 and mi into contact with terminals 0, m", respectively. Thereu-pon contact with terminal I, closes circuit through wire 179 and one of the coils of valve V7 So as to operate through cylinder 124, piston rod 123 and the associated parts, to open the blow mold 108 so as to permit the withdrawal of the completed article which -is therein. Thereupon Contact with terminal i closes circuit through wire 182, terminal fz', terminal z", and wire 172 through one coil of valve V1 so .as to cause 'an actuation of piston 16 to open the sections of the parison mold 18 vand thus ex- Thereupon contact with terminal lc closes circuit through wire 180 and one coilv of valve V7 to close the blow mold around the parison. Thereupon contact with termlnal l closes circuit through Wire 186, terminal dh terminal Z, and wire 166 to actuate valve' V3 and admit the air through pipe 81 and passages 80, 79 and 58 into the 'cavity of the neck ring and the cavity of the parison so as to expand the parison into the blow mold.

4the completed article so that, when contact is made with terminal n to close circuit throughwire 184 and one coil of valve V6, thecylinder 116 and .associated parts, acting to swing carrier 106 back to its normal position, will permit the completed article to be carried away in the blow mold. Thereupon contact with terminal 0 closes circuit through wire 190,' terminal 0., terminal o',

wire 189 and one coil of valve V2 to close the neck mold. `The brush 15S then moves into contact with terminal 72 which closes circuit through wire 191', terminal ep, terminal p', wire 173 and one coil of valve V2 to actuate piston 1G and cause the blank mold 18 to close. Brush 158 tl1en moves into contact with terminal (1 thus closing the circuit through wire 178 and the coil of valve V5 so asto cause an actuation of cylinder 101 and associated parts to swing car.- rier 14 back to its normal position, valve V again contacting with the cam 10-1', during the swinging of the Acylinder 101, so as to eX- haust the air from the cylinder during the nal portion of the return movement of carrier` 14. This brings the parts back to the starting position and a contact with terminal r causes an actuation of the oil-squirting ump 194 in the manner already described.

It Will b e readily understood that the unit, comprising the blank mold, the neck mold, the blow mold and 4the associated parts, may be very readily duplicated or arranged in multiple in such manner as to be brought successively to a single filling position. For instance, I have shown in Fig. 12 a plan,

,diagmmmaticallyu of such an arrangement mounted upon a horizontally rotatable table i 210 and capable of passing. the parison molds in their receiving positions successively beneath a shearing mechanism 211 which may, if desired, be of such form as is now commonly used for operation upon a stream of glass owing continuouslyA to 'the cutting mechanism.
